RERAILING-FRO G.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed October 20, 1917. Serial No. 197,715.

To all whom it may concern.

Be it known that I, CI-IARLns B. SULLIVAN, a citizen of the United States, residing at Rosedale, in the county of Wyandotte and State of Kansas, have invented a certain new and useful Improvement in Rerailing Frogs, of which the following is a specification.

My invention relates to improvements in rerailing frogs.

The object of my invention is to provide a rel-ailing frog which has great strength and durability, which is economical to manufacture, which may be easily handled and readily placed in and removed from operative position.

My invention provides further novel and efficient means by which the derailed wheels may be easily and surely guided into their operative positions upon the rails.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate the preferred embodiment of my invention,

Figure 1 is a plan view,showing a pair of my improved rerailing frogs applied to a railroadtrack.

Fig. 2 is a side elevation, partly broken away, of what is shown in Fig. 1.

Fig. 3 is a cross section of a railroad track, partly broken away, having a pair of my improved rerailing frogs mounted thereon.

Fig. at is a side elevation of the inner frog, partly broken away, shown mounted on a track adjacent to one of the rails.

Fig. 5 is a cross section 011 the line 5-5 30f Fig. 1.

Similar reference characters designate similar parts in the different views.

The frog which is adapted for replacement of the wheels which are off the track at the outer side thereof, preferably comprises two end members 1 and 2 and an intermediate member 3. These members are adapted to be secured to the ties 5. For securely interlocking the three ment here to each other in the operative position, the members 1 and 3 are preferably provided with projections 6 and 7 respectively, which are adapted to be respectively fitted into recesses provided. in the adjacent recesses of the members 31 and 2.

Respectively mounted in the members 3 and 2 are set screws 4 and 9,,which are 4 by spikesand 7 respecand also hold the rail from being crowded laterally upon the ties 4.

The upper side of the rerailingmembers 2, 3 and 1 are provided respectively with flanges 12, 13 and 14:, which are disposed in alinement with each other and form a continuous wheel supporting flange, the en trance portion 12 of which is inclined and the exit portion 1 1 of which is disposed in substantial alinement with the ball of the rail 10 at the extreme end of such exit portion.

For guiding the tread of the car wheels which are to be replaced onto the wheel supporting flanges 12, 13 and 14, the members 2, 3 and 1 are provided respectively on their upper sides with guards 15, 16 and 17, which form with the flanges 12, 13 andl a groove 18 which at its entrance end, on the member 2 is laterally flaring and inclined. The exit end of the groove 18 extends clear across the member 1 at the inner side of and paral lel withrthe ball of the adjacent rail 10'.

When a car wheel enters the flaring part of the groove 18, the guard 15 will'engage the flange of the car wheel 19 and will force the tread of the wheel onto the flange 12, from which the wheel will pass onto the rail 10 over the flanges 13 and 1 1, the exit end of.

the latter inclining to the upper surface of the ball of" the rail. The flange of the wheel will pass through the groove 18tothe inner side of the ball of the adjacent rail.

The member 3 is provided with an inclined portion 20, which overlaps the ball of the rail, and which permits the rear wheels, such as may not have been derailed to ride easily from the adjacent rail upon and over the portions of the frog which overlap and are above the ball of the rail. That portion of the groove 18 which is at the inner side of and parallel with the ball of the rail, permits of the unobstructed passage of the flanges of the wheels which have not been derailed. 3

The members 2, 3 and ft are preferably provided with handles 21, 22 and 23 respectively, said handles being located at the outer edges of said members. These handles provide for the ready handling of the frog members in assembling the members into their operative position or removing them from such position.

The frog which is to be used at the inside of the rail for replacing the wheels which are between the rails, preferably comprises two members 24 and 25, which are spiked to the ties 4 between the rails 10 and which are interlocked together in the same manner as are the members 2 and 3, the member 21 being provided in one edge with a recess adapted to receive a'projection 26 which is provided on the adjacent edge of the member 25. In the member 2a is mounted a set screw 27 which bears against the projection 26.

The member 24 corresponds in construction to the member 2. It is provided with a flange 28 corresponding to the flange 12 and which alines with a flange 29 on the upper side of the member 25, the flanges 2S and 29 serving as a guard for forcing the tread of the adjacent ear wheel 19 upon a flange 30, which alines with a flange 31 disposed parallel with the flange 29 on the member 25, the flanges 31 and 29 being spaced apart from the ball of the adjacent rail 10 to permit the passage of the flanges of such wheels as are not derailed.

The flanges 30 and 31 form a groove 32, for the passage of the flanges of the derailed wheels, in connection with the flanges 28 and 29. 'The groove 32 at its entrance end is inclined and flaring.

,Derailed wheels entering the groove 32 will pass up the inclined entrance portion thereof and will be forced by the guard flanges 28 and 29 onto the flanges 30 and 31, which will support the treads of the derailed wheels until the latter have passed onto the adjacent rail 10.

. For convenience in handling, the members 24'and 25 may be provided at their inner edges respectively with handles 33 and 34:.

The side walls of the groove 11 in the member 1 are slightly downwardly flaring, so that the member may be easily dropped into operative position, and is readily lifted from engagement with the rail.

1 do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is 1..A rerailing frog having a portion adapted to overlap a rail, the underside of said portion having a longitudinal groove adapted to receive the rail, the walls of the groove being adapted to embrace the sides of the rail, whereby the rail and the frog are held from relative lateral movement, the frog being movable vertically into and out of engagement with the rail, provided on its upper side with a wheel supporting flange having an inclined entrance portion, and having an exit portion which is substan tially in alinement with the ball of the rail when the frog is in operative position.

2. A rerailing frog having a portion adapted to overlap a rail, the underside of said portion having a groove adapted to receive the rail, the walls of the groove being adapted to embrace the sides of the rail, the frog being movable vertically into and out of engagement with the rail, provided on its upper side with a flange for supporting a car wheel, the flange having an inclined entrance portion, an exit portion substantially in alinement with the ball of the rail when the frog is in operative position, and a guard adapted to engage the flange of the wheel and arranged to force the wheel and to retain it upon the flange, the guard and flange forming between them a groove for receiving the flange of the car wheel. the groove being flaring at its entrance end, the exit end of the groove being at the inner side of and parallel with the ball of the rail when the frog is in the operative position on the rail.

3. A rerailing frog having a portion adapted to overlap the top of a rail, the under side of said portion having a groove adapted to receive the rail, the frog being movable vertically into and out of engagement with the rail, the upper side of the frog having a wheel supporting flange, the entrance portion of which is inclined and the exit portion of which is in substantial alinement with the ball of the rail, the frog having on its upper surface a guard adapted to engage the flange of a wheel, the guard forming with said flange a groove adapted to receive the flange of the wheel. the flang and guard forming between them a groove for receiving the flange of the wheel. the entrance end of the groove being inclined and flaring, and the exit portion of the groove being parallel with and at the inner side of the ball of the rail, when the frog is in operative position, the evit portion of the groove extending clear :v'ross the por tion of the frog which overlaps the rail.

In testimony whereof I have signed my name to this specification.
